WARNING
PRE-SAFE ®
Brake cannot always clearly iden-
tify people, especially if they are moving. In
these cases, PRE-SAFE ®
Brake cannot inter-
vene. There is a risk of an accident.
Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE ®
Brake warns you.
To maintain the appropriate distance to the
vehicle in front and thus prevent a collision, you
must apply the brakes yourself. G
WARNING
PRE-SAFE ®
Brake does not react:
R to small people, e.g. children
R to animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As a result, PRE-SAFE ®
Brake may neither
give warnings nor intervene in all critical sit-
uations. There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake.
In the event of snowfall or heavy rain, detection can be impaired.
Detection by the radar sensor system is also
impaired in the following situations:
R dirt on the sensors or obscured sensors
R interference by other radar sources
R strong radar reflections, for example, in multi-
storey car parks
R a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different line
Detection by the camera system is also impaired
in the following situations:
R dirt on the camera or obscured camera
R glare on the camera system, e.g. from the sun
being low in the sky R
darkness
R if:
- pedestrians move quickly, e.g. into the path
of the vehicle
- the camera system no longer detects a
pedestrian as a person due to special cloth-
ing or other objects
- a pedestrian is concealed by other objects
- the typical outline of a pedestrian is not
distinguishable from the background
Following damage to the front end of the vehicle, have the radar sensor settings and operation
checked at a qualified specialist workshop. This
also applies to collisions at low speeds where
there is no visible damage to the front of the
vehicle.
Following damage to the windscreen, have the
configuration and operation of the camera sys-
tem checked at a qualified specialist workshop.

This function will issue a warning if: R at a speed of around 30 km/h or more, the
distance maintained to the vehicle travelling
in front is insufficient for several seconds
The · distance warning lamp will then
light up on the instrument cluster.
R at a speed of around 7 km/h or more, you
rapidly approach a vehicle in front or a pedes-
trian
An intermittent warning tone will then sound
and the ·distance warning lamp will light
up on the instrument cluster.

R during driving
R when you are using HANDS-FREE ACCESS
R when the external door handles are touched
R during convenience closing Key

Tailgate obstruction detection with
reversing function
Vehicles with remote tailgate closing:
The tailgate is equipped with automatic obstacle detection with reversing function. If a solid
object blocks or restricts the tailgate when auto-
matically opening, this process is stopped. If a
solid object blocks or restricts the tailgate when
automatically closing, the tailgate automatically opens again slightly. The automatic obstacle
detection with reversing function is only an aid.
It is not a substitute for your attention when
opening and closing the tailgate. G
WARNING
The reversing function does not react:
R to soft, light and thin objects, e.g. fingers
R over the last 8 mm of the closing path
In these situations in particular, the reversing
function cannot prevent someone being trap-
ped. There is a risk of injury.
When closing, make sure that no body parts
are in the closing area.
If someone is trapped:
R press the Fbutton on the key or
R pull or push the remote operating switch on
the driver's door or
R press the closing or locking button on the
tailgate or
R push the top of the star on the tailgate
Vehicles with HANDS-FREE ACCESS:
It is also possible to stop the closing process by
making a kicking movement under the rear
bumper. Opening and closing automatically
